Hello RonF, this is Stacy from Simpson Strong-Tie. I am pleased to hear the CDT10S Manual Dispensing Tool performed as expected and satisfied your needs, though I am sorry to hear about your caulking gun and the lost tube of SET-3G. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you.
